In preparation for F29, I went to define new build and srpm-build groups to remove gcc an gcc-c++ and remain aligned with Fedora.

However, `koji add-group f29 build` does nothing--it doesn't add the group to the database (associated with the f29 tag). I can also find no errors in the Apache or PostgreSQL logs.

It's been a while since I've needed to modify groups which are typically inherited from the previous version tag. Is there something I'm missing?
